Patented July 28, 1936 lTED s-TATEs Thisinvention relates tocooling devices, and more particularly to devices for use inconne'ction with internal combustion engines "and other mechanical equipment where a liquid is used a cooling agent. 3

One of the prime objects of the invention' is to design a simple and efficient cooling device which readily cools the liquid circulating through it, and: which when used in connection with ventional radiator and the fan-used in" connection therewith.

Another object is to design-a simple, practical,- and economical device whi'ch can be readily con- 15 nected to an engine or other apparatus, andpromerous arrows showing the'- direction of flow of air through the device. v

A further object is to provide a-'-li'quid c "1% ing means sodesigned that washed can be supplied'to the carburetor of the-engine;-

With the above and other object's n view, the present invention consists'in the combi'nation and arrangement of parts, hereinafter more fully described, illustrated in thenaccompanyi'r'ig draw ings, and particularly pointed 'out in'the' append ed claims, it being understood that changesjmay be made in the form, size, proportion; and' niirior details of construction, without departing from the spirit, or sacrificing any'of the-advantages no of the invention.

, Referringjnow specifically which Ihave shown the preferre'd"embodiment of my invention, the numeral Ill -'indicates a pref5 55*e'rably cast'pump'supporting bracket which is internal combustion engines eliminates the con-- mounted on a vehicle frame H or other suitable support. This is formed as clearly shown in Figs. 2 and 5, and a pump l2 is secured thereto by means of bolts or the like. A bearing I3 is mounted on the frame H in any approved man- 5 ner, and a drive shaft M is journaled therein,'a bevel gear 15 being mounted on said shaft, meshing with and driving a miter gear l6 which is mounted on a vertically disposed shaft ll, said sh'a'ftbeing journaled in bearings as usual; 3

A drain base support I9 is mounted on the frame I I, and includes the drain base 20, said base being formed with an inclined bottom 2-! to which a drain spout 22 is connected, bolts 23 being weldedor otherwise secured to the bottom and support a plate 24 on which the bearing 25 is mounted, the shaft [1 being journaled in said bearing.

The upper end of the drain base 20 is shouldered'as at 26, and a baffle 2'! is mounted on 2 said shoulder, a plurality of openings 28 being provided in the side Wall of said base for ad lnitting air thereto, and a collar 29 is mounted on the shaft l1 above the hub 2H for a purpose to be presently described. I 7

7 A preferably sheet metal shell is mounted on the d'r'ain'base and comprises upper and lower sections 30 and 3| respectively, the ends being flanged as at 32, and bolts 33 serve to secure themfrigidly together, thelower end of the sec- 30 tion 3lf being conical shaped as at 34 to fit the shoulderediend of the drainbase, a pluralityof openings 35'beingprovided in this lower section, and vertically spaced baffles 36 are secured therein, the baflie 36 being formed with a rirn36 35 to' confine'the spray and water as it circulates through the device.

A spider 31 is interposed between the flanges 32' of the shell sections and is formed with a hub 38 in-Whic1'i'a' taper bearing 39 is mounted, 40 the upper end'of' the shaft I! being journaled therein. I v i A plurality of disc shaped cones 40 are mounted on the shaft I! in spaced apart relation, and separators 4| are interposed between said cones to properly space them on the shaft, the rims of thecones being disposed beneath the edges of the baffles sothat water and spray dripping from the baffles 36 successively drip from one cone into the next. 0.

A similar baffle 42 is mounted in the upper shell section 3!, and this is also formed with a rim 43, saidbafile surrounding a spray cup 44 which is formed with a plurality of spray openings 45,

said cup being mounted on the upper end of the shaft I1, which is threaded to receive the nut 46, so that the parts are rigidly'held in assembled relation.

The upper end of the section 30 is also conical shaped and opens into a flared extension 48 in which a venturi 49 is adjustably mounted, the throat of the venturi being constricted as at 50, and bolts 5! are secured to the side walls thereof, these bolts projecting through slots 52 provided in the walls of the extension 48, guides 53 being also secured to the extension and are slotted in a similar manner, so that the venturi can be raised or lowered as desired, Wing nuts 54 serving to secure it in adjusted position. I

A bearing 55 is provided on the plate 56 which is interposed between the end of the bracket l and the pump, and the end of the shaft I1 is journaled therein, the pump rotor 51 being' secured on said shaft.

A filter 58 is mounted on the frame directly Y it will be obvious that the velocity of air traveling through the device can be regulated accordingly. A hanger 63 serves to secure the pipe in position, a lip 64 being provided as shown so that liquid and condensation will drip into the spray cup. 7,

The return water line from the motor is indicated at 65 and discharges into the driven spray cup 44, the liquid being thrown, by centrifugal force, through the spray openings 45 and against the baflle 42, the rim 44 limiting the upward fiow, the water thence drips down into the upper cone 4D, thence being thrown in a thin sheet against the next bafiie-36 until it reaches the inclined bottom 2|, thence it discharges through the discharge spout 22 into the filter 8 and is pumped back to the engine (not shown) by means of the pump l2.

Air enters through the openings 28 and 35, being drawn upwardly through the sheets of water which are thrown by the cones against the bafile '36, the position of the venturi with relation tothe end of the exhaust pipe determining the draft.

An air intake pipe 66 communicates with the hooded intake or hanger 63, said hanger serv-' ing as a shield and is cupped as shown in Fig. 9 of the drawings to exclude spray and water, said pipe leading to the carburetor of the engine (not shown) so that washed air is supplied at all times, and the air is further preheated by reason of its circulating around and contact with met-a1 sections if desired, it is easy to assemble, is extremely efficient in operation, and will cool large volumes of water quickly and efiiciently,

From the foregoing description it will be obvious that I have perfected a very simple, practical, efiicient, and economical cooling device for.
